a light, beam on the object being treated,

whereby to enable the operator to clearly observe the surface beingtreated, especially in dark-places wherein the room artificial lightingsystem is insuflicientto render such surfaces clearly visible forefficient coating.

What I aim to do, is to provide an excep-,

tionally' simple and inexpensive electric lamp enclosed in a housingwhich is especial- .y constructed to permit it to be attached to a.conventional form of. paint spray gun without requiring alterations ofthe stock Darts of the gun.

The lamp attachment is characterized by exceptional simplicity,,inexpensiveness of manufacture, efficiency in construction, case nattachment and. removal, and durability.

An important factor to be considered in he construction of the noveltyis. the arangementof the light or lamp casing along- :ide of the paintconducting barrel of thegun in order to take advantage of the-heat'adiating' from the light for heating the mint as it passes through the'barrel to cause t to flow freely. i

Other features and advantages of the in- 'ention' will become apparent'from the folowing description and drawings. r

In the accompanying drawings forming a art of this application, and in-which like .umerals are employed to designate like arts throughout thesame Figure 1 is a side elevation of the convenional gun showing thelamp attached to one ide of the barrel thereof. v Fig. 2 is a rear endelevation-of the same. Fig. 3 is a top plan view. Fig; 4 is an enlargedlongitudinal section irough the attachment per se. Fig. 5 is'a crosssection on the line 55 of ig. 4, looking from left to right.

Fig. 6 is a fragmentary perspectiveview iowin the light casing and" lensretaining im, with the 'pin and bayonet slot connecon.

The gun represented in the drawings,is

5 conventional construction, being of the r A De'vilbissconstruction. Itncludes mile 1, paint barrel 2, air. hose connecconsidering this figure,

tion 3, 'fluid hose connection 4, universal air cap and nozzle head 5,together with fluid needle adjusting screw 6 and handle retaining'nut 7.Incidentally, the handle inthis case is provided with a sleeve at itstop which fits over the adjacent end of the barrel and is held in placeby the nut 7. i

I mention this because the attachment, which is generally designated bythe reference character- 8, is closely associated with these details.The attachment as is better shown in Fig. 4, comprises a cylinder 9, alight bulb 10 located therein, a socket 11, a switch chain 12, andsupport and connecting member 13. The latter is provided with'a circularbase 14 which is riveted to the closed end of the cylirider.- Theoppositeend of the cylinder is provided f with an inturned flange, andthe lens 15 is held against this by a removable retaining rim 16.

with a bayonet slot 17 as shown in Fig. 6 and the lens retaining rim is.provided with a pm 18 which fits into this slot and holds the ens inplace. The electricity conductor is represented 'by 'the. referencecharacter 19. ln this connection, it will be noticed that a suitableretaining member 20 is providedat this end of the cylinder and serves tohold an attaching disk 21 in place. This disk is provided with an arm 22terminating in a connecting ring 23. As shown better m Fig. 3, thisconnecting ring- 23 is arranged between the'sleeve 24 on the'upper endof the handle 1, -and the retaining hat 7. I

These details are existing ones on the ordinary gun and I take advantageof-this because the attachment therefore requires no. alterations of thestock parts. While it will be noticed that the length of the device isslightly less than the length of the adjacent portion of the gun, andthat the lens terminates in inwardlys aced relation to the spray head,or nozzle.- oreover, the'lamp cylinder is in metallic contactwith thegun barrel and as Incidentally, the cylinder is provided before stated,it is important to note ,ihatthat the light has the additional functionof heating the paint as it passes through "the barrel, thuscausin it toflow freely. This is a pointiofnovefiy to be emphasized.

It is plain to be seen that withthis construction theoperator can. coatthe surface treated in a'moreelficient manner due to the factthat' thebeam of light from the lamp will be projected onto'the surface and willrender it clearly visible under all conditions.

It is believed that the construction, and use, and advantages of theinvention will be clear to persons familiar with guns of this character.Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown anddescribed,'it is to be understood that minor changes coming within-thefield of invention claimed ma be resorted to if desired.

Ilaving thus described my invention, what I claim as new is As a'newroduct of manufacture, a lamp attachment or Saint spray guns comprisinga cylinder close at one end andhaving an inturned flange at its oppositeopen end, a

- by said lamp socket in the cylinder, a lamp carried socket, aconnecting stem carrie by the socket and including a circular basefastened to the closed end of the cylinder, switch operating meanscarried by the lamp socket, a source of current supp] associated withsaid socket, a lens ring against said inturned flange, a retaining rimfor the lens detachably connected wit the cylinder, a disk bearingagainst the outer surface of the closed end of the cylinder and havin acentral opening, having an arm exten ing from one side, and an attachingring carried by the outer end of the am.

In testimony whereof I aflix my signature.

GEORGE a. WEBER.
